NASA has confirmed the upcoming milestones for its historic Artemis II mission—the first crewed flight of the Space Launch System (SLS) rocket and Orion spacecraft, sending four astronauts on a lunar flyby for the first time in over 50 years—with rollout and Wet Dress Rehearsal (WDR) to set the stage for a potential launch in February.

Work for now continues daily at Kennedy Space Center on a new mobile launch tower that has already cost more than $1 billion. But the Artemis moon mission it is intended to serve may never happen if President Trump’s plans for NASA come to fruition.
